SPECIFICATION forming part of Letters Patent No. 633,809, datedSeptember 26, 1899. Application liled June 15,1899. secure. 720,621.names.)

To all whom it may concern:

Be it known that I, HERBERT F. COOK, a citi= zen of the United States,residing at Cleveland, in the county of Guyahoga and State of Ohio, haveinvented a certain new and useful Improvement in Steam-Traps, of whichtrap-casing, but which may he opened positively when desired.

The invention consists in the construction and combination of partshereinafter described, and pointed out definitely in the claim.

In the drawings, Figure 1 is a sectional side elevation on line 1 1of'Fig. 2; and Fig. 2 is an end view of the trap, looking in the vdirection of the arrow in Fig. 1.

Referring to the parts by letters, A represents the casing which formsthe body of the trap and has an inlet-opening a and two threaded tubularprojections a a. for con? necting the water-gage. One end of-the casingis closed by a plate B, which is fastened thereto by screws. 7 screwedinto a threaded outlet-openingin said plate. which an escape-pipe may beconnected. This plug has an internal annular valve-seat c, and itcontains also a valve D for engagement with said seat. This valve is ofa wellknown form, having guideways at. Its stem (1 projects into thecasing and has a'groove d with which the lower forked endv e of abell-crank lever E engages, whereby the rocking of the lever will movethe valve toward or from its seat. This lever is pivoted to ears I) onthe inner side of plate B, and its arm e is attached to a float F. Whenthe float is lifted by the accu mulating water, the valve is drawn fromits seat. As the float falls the valve is moved toward its seat.

A tubular plug 0 is This tubular plug has an elbow c, to

It is frequently desirable to draw off the water in the casing, and forthis purpose a screw G screws through the end cap H of the plug 0 (saidscrew being embraced by astuifing-box h) and is in line with the valve.When this screw is screwed in, its end on gages directly with the end ofthe valve and moves it from its seat. o It is not claimed that the valveis new, nor that it is new to employ a lever operated by a float toautomatically operate the valve; nor is it claimed that means have notbeen heretofore used to positively move a float operated valve from itsseat.

The chief merit of the present invention is due to the fact that thesame screw-plug which contains the valve contains also the means forpositively moving the valve from its seat, that these means andthe valveare of the simplest and cheapestform, and that thecombination is novel,cheap, and effective.

Having described my invention, I claim' In a steam-trap, the casing, theplate B which closes the opening through one end of the casing,'andwhich is provided upon its inner side with the ears 2), the bell-cranklever pivoted between said ears and provided at its upper end with thefloat F, and which lever is provided-with the lower forked end 2, andthe valve D provided with the grooved stem at, combined with the end capH, screwthreaded near its inner end, and which cap has its inner end toproject through the plate B a suitable distance just below the ears I),a
